Mrs. Haddock - Malcolm Haddock's mother. An invalid busybody who hired Isolde Marlowe as a companion (mainly to deliver the town gossip to her and provide someone of the Female Persuasion to talk to).
Evans - The Haddock's loyal and laconic butler who, along with the rest of the staff, knows about the Family Affliction. Used to be a battlefield surgeon, so he knows how to patch people up if need be.
Fiona Haddock - Fiona is the most like her mother, being a kind spirit who is a little more softspoken. She's married to a fellow named Roger and they have five little ones.
Ainslay Haddock - Ainslay is the Negative Nancy sibling married to a hypochondriac werewolf named Felix. She doesn't intend on having any children in the near future since she's a bit OCD herself and is always complaining about things getting dirty.
Douglass Haddock - Douglass is the brother who died along with his father Alistair at sea. He was the one who kept the siblings together, being the serious arbitrator of the group. He left behind a fiancee named Celeste who hasn't married since his death.
Grant Haddock - Grant is the wild child of the family who loves to brawl just for the heck of it, so he signed up for the British Army. He returned from fighting overseas in the war between France to act as a training sergeant in the current timeline of the story. He's also something of a ladies' man, breaking many a heart during his travels overseas.
Monroe Haddock - Monroe prefers reading to fighting and owns a tailor shop in a small town. He and his wife, Anna, are expecting their first set of children.
Alistair Haddock - The husband of Miriam and father to the Haddock clan, Alistair was a good man who ran his household with both a firm and merciful hand. He did his best to see that all of his children received their fair share of his attention, and that the staff were looked after. He died with his son, Douglass, (arguably his favorite child) at sea when the ship they were on was blown out of the water by marauders.
